Summary: in this tutorial, you will learn how to implement the command design pattern in ABAP with a code sample.
Problems
In some programming contexts, you need to issue a request to an object without having knowledge of the operation being requested or the actual object that performs the request.
Intent
- Encapsulate a request as an object, thereby letting you parameterize clients with different requests, queue or log requests, and support undoable operations.
Discussion
- Command design pattern allows you to decouple the object that invoke the operations from the object that actually performs the operations.
